With over six years of market presence and more than 200 successfully delivered products, the company serves a broad range of clients including major international brands. Their business model focuses on custom software development, emphasizing collaboration with UX designers to ensure high-quality, secure, and user-friendly digital solutions. The company maintains a strong market position supported by positive client rankings and a commitment to agile methodologies. Technically, the website reflects a mature digital infrastructure utilizing modern technologies such as PHP, React, React Native, and various backend tools like Redis and Rabbit MQ. The site is well-optimized for performance, mobile responsiveness, and accessibility, indicating a high level of digital maturity. The use of Google Tag Manager and Iubenda for cookie consent demonstrates awareness of privacy and analytics best practices. From a security perspective, the website enforces HTTPS and implements a cookie consent mechanism, but lacks explicit security headers and a published security policy or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the content. The domain registration details align well with the business claims, supporting legitimacy and trustworthiness. Overall, Flying Bisons presents a professional and credible online presence with strong technical and business foundations. Strategic improvements in security policy transparency and enhanced security headers would further strengthen their security posture and compliance standing.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Business context

Business profile

Flying Bisons operates in the technology sector, targeting businesses requiring custom web and mobile development. Their competitive advantage lies in their collaborative approach, agile project management, and a strong portfolio of high-profile clients. Revenue streams likely derive from project-based development, maintenance contracts, and SLA services. The company demonstrates growth through client retention and positive market reputation, as evidenced by their Clutch rating and extensive client list. Partnerships with major brands and presence on professional social platforms indicate a robust ecosystem. Operationally, the company emphasizes quality, transparency, and reliability, which are key to sustaining their market position.

Security posture

The current security maturity level is moderate to high, with HTTPS enforced and cookie consent implemented. However, the absence of explicit security policies, incident response information, and security.txt files indicates gaps in formal security governance. No critical vulnerabilities or exposed sensitive data were found, and the contact form includes consent mechanisms, reducing risk. Compliance with GDPR is supported by privacy and cookie policies. Incident response readiness and security culture could be improved by publishing dedicated security documentation and contacts. Overall, the security posture is adequate for the business type but can be enhanced with additional transparency and technical controls.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to improve protection against common web attacks.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable dependencies.
  5. Enhance form security with CAPTCHA or other anti-spam measures and ensure robust input validation.

Technical notes

Notes

The website is built on a modern technology stack including PHP for backend, React for frontend, and React Native for mobile applications. It uses databases like SQL and MongoDB, and messaging systems such as Rabbit MQ and Redis, indicating a scalable and robust infrastructure. The site is optimized for fast loading and mobile responsiveness, with good SEO and accessibility practices. The use of Google Tag Manager and Iubenda for analytics and cookie management reflects a mature approach to data collection and privacy compliance. No CMS was explicitly detected, suggesting custom development. Hosting provider details were not identified from the content. Overall, the technical implementation supports the business goals effectively with room for security enhancements.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
